Abstract (en)

[origin: EP0125539A2] Mixtures containing 1,8-cineole are treated with hydroquinone to complex with and precipitate the 1,8-cineole. The complex in a crystalline form is separated from the mixture and dissociated to give 1,8-cineole which may be isolated in high-purity form by filtration or distillation.
